Question

我有一个与休眠 2 级缓存相关的问题。它适用于 getById 方法，但不适用于其他方法：

这是我的代码：

@Configuration @EnableCaching public class CacheConfiguration {
@Bean
public javax.cache.configuration.Configuration<Object, Object> jcacheConfiguration(JHipsterProperties jHipsterProperties) {
    MutableConfiguration<Object, Object> jcacheConfig = new MutableConfiguration<>();
    Config config = new Config();
    config.useSingleServer().setAddress(jHipsterProperties.getCache().getRedis().getServer());
    jcacheConfig.setStatisticsEnabled(true);
    jcacheConfig.setExpiryPolicyFactory(CreatedExpiryPolicy.factoryOf(new Duration(TimeUnit.SECONDS, jHipsterProperties.getCache().getRedis().getExpiration())));
    return RedissonConfiguration.fromInstance(Redisson.create(config), jcacheConfig);
}

@Bean
public HibernatePropertiesCustomizer hibernatePropertiesCustomizer(javax.cache.CacheManager cm) {
    return hibernateProperties -> hibernateProperties.put(ConfigSettings.CACHE_MANAGER, cm);
}

@Bean
public JCacheManagerCustomizer cacheManagerCustomizer(javax.cache.configuration.Configuration<Object, Object> jcacheConfiguration) {
    return cm -> {
        createCache(cm, com.mycompany.myapp.repository.UserRepository.USERS_BY_LOGIN_CACHE, jcacheConfiguration);
        createCache(cm, com.mycompany.myapp.repository.UserRepository.USERS_BY_EMAIL_CACHE, jcacheConfiguration);
        createCache(cm, com.mycompany.myapp.domain.User.class.getName(), jcacheConfiguration);
        createCache(cm, com.mycompany.myapp.domain.Authority.class.getName(), jcacheConfiguration);
        createCache(cm, com.mycompany.myapp.domain.User.class.getName() + ".authorities", jcacheConfiguration);
        createCache(cm, com.mycompany.myapp.domain.Company.class.getName(), jcacheConfiguration);
        // jhipster-needle-redis-add-entry
    };
}

private void createCache(javax.cache.CacheManager cm, String cacheName, javax.cache.configuration.Configuration<Object, Object> jcacheConfiguration) {
    javax.cache.Cache<Object, Object> cache = cm.getCache(cacheName);
    if (cache != null) {
        cm.destroyCache(cacheName);
    }
    cm.createCache(cacheName, jcacheConfiguration);
} }

公共类 CustomRegionFactory 扩展 RedissonRegionFactory {

@Override
protected RedissonClient createRedissonClient(Map properties) {
    Config config = new Config();
    config.useSingleServer().setAddress("redis://127.0.0.1:6379").setRetryInterval(1500)
        .setRetryAttempts(3).setConnectTimeout(10000)
        .setClientName("client1");

    return Redisson.create(config);
}

}

实体：

import javax.persistence.*;

import java.io.Serializable;

/**

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "name")
    private String name;

    // jhipster-needle-entity-add-field - JHipster will add fields here, do not remove
    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public Company name(String name) {
        this.name = name;
        return this;
    }

    public void setName(String name) {
        this.name = name;
    }
    // jhipster-needle-entity-add-getters-setters - JHipster will add getters and setters here, do not remove

    @Override
    public boolean equals(Object o) {
        if (this == o) {
            return true;
        }
        if (!(o instanceof Company)) {
            return false;
        }
        return id != null && id.equals(((Company) o).id);
    }

    @Override
    public int hashCode() {
        return 31;
    }

    @Override
    public String toString() {
        return "Company{" +
            "id=" + getId() +
            ", name='" + getName() + "'" +
            "}";
    }
}
